Abstract

•Reversals of magnetization and exchange bias field were observed in YbCrO3.•The normalized magnetization is linear with the normalized magnetization shift.•The reversals are due to the interaction between the canted Cr3+ and Yb3+ moments.

Reversals of magnetization and exchange bias field were observed around 19 K in polycrystalline perovskite chromite YbCrO3. Both the reversals can be elucidated based on the antiferromagnetic interaction between the ferromagnetic component of Cr3+ moments and the Yb3+ moments. The low field magnetization exhibits a perfect linear correlation with the magnetization shift resulted from the exchange bias effect. Distinguished from other exchange bias systems, the dependence of HE at 10 K on the cooling field shows an almost undamped feature up to 85 kOe, indicating the stable exchange bias states in respective temperature region.
